Firstly the article does not match the picture. On the one on the Amazon site (pictured) it is the original. But in truth, I have strong doubt, it seems that it is a copy. Certainly there has the logo hologram SONY ERICSON, but the sticker is positioned incorrectly, badly stuck in the rounding. Still, for the price, we know very well that we will have the Chinese. Otherwise, we'll see the use. The original held seven years. It surprised me that it would do the same ...
Well I changed my mind after several months of use. It is indeed a battery varies and takes into both the load as the original. It is simply a packaging made by SONY ERICSON. Everything is fine.
